Gatos apparently had the anchor on one side only, but Trump's kit has them on both sides. I haven't seen any builds, or reviews of the kit, so does it have other problems?

Lack of diesel exhausts, no flood vents, superstructure aft end is wrong shape, no prop guards (note can be welded in place like early as builts or removable guard), guns suck to be blunt, main gun location varied so might need to build or remove sponson, aft torpedo loading hatch lacks hinge/spring detail. Nautilus had flood vent scribing guides and you can use them to locate the holes then remove the guide and cut through.

Tambor class sub. Especially since the Tambors had an all wood deck and anchors on both sides...as in the Trumpter kit. Might be wise to measure the kit's hull. Gato should be 26" in 1/144. Tambor would be 25 5/8".
This conversion would be a WHOLE LOT EASIER THAN 1/72.

These two early Electric Boat Gatos carried their anchors on both sides of the hull. They later lost the portside anchor during wartime refits. Portsmouth/Mare Island boats and Electric Boat/Manitowac Gatos differed in a number of ways. One was the location of the (eventually) single anchor. Not all Gatos had the full length wooden deck, so again, the kit is best for those early high fairwater units.

As others have said, there are some issues with the kit. However, it is a decent build - not superb, but decent - out of the box. As long as you know it best represents Gato and Greenling as built and commissioned, early 1942, its fine. Nautilus Models has some conversions if you want to change out a few things. It can certainly use some aftermarket goodies to spruce it up.
